To all whom it may concern:

.Be it known that I, JOHNC. WANDS,' aeitiam of the United States, residing at the city ofSt. Louis, State of Missouri, have invented a certain new and useful Improvement in Devices for Relieving Pressure 'on Motor-Vehicle" Tires, of which the following is a full, clear, and exact description,;such as will enableth:

elS skilled in the m to which it appertains to make and use thesame,-reference being had to the accompanying drawings, forming apartof cross-sectional view on the line 3 3 of Fig. 2.

4 a fragmentary elevational view of a modified form of t re-relieving dev1ce.. Fig. 7 ls'an Fig. 4 is a cross-sectional view on the line 4 1 of Fig. 2. Fig; 5 is a side elevationalview of two of the devices'connected together. Fig. 6 is end view of the yielding bed-clamp. vFig. 8

is'a cross-sectional view on theJine 8 80f Fig. 6', and Fig. 9 is a perspective view of the interior of the premises for the temporary storage of motor-vehiclesin which isarrauged a modified form ofmy invention.

This invention relates to a ti rerelieving de-' Vicethat is to say, of a device for relieving pressure on the tires of motor-vehicles when the vehicle is not being used. As is well known, motor-vehicles are generally equipped with pneumatic tires and the wear and deterioration of the tires due to the dead-weight of the vehicle-body, the driving-gear, &c.,

tends to materially shortenthe life of the tires. It is the purp oseof my invention to provide means wherebythe pressure due to the weight of" the vehicle=body maybe relieved when the vehicle is not beingused, and thus prolong the life of the tires. 1 j

i In the drawings I have illustrated one form I frame in the formof a truss and having a base-flange 2.

i 3 designates inclined braces which are connected to the trussed frame and the base-- flanges 2. The frame is preferably constructed of a malleable casting so that it may be light, durable, and ornamental. However, 1 reserve-the right to construct the frame of any other material, if desired. The top of the frame is provided with ,a horizontal. interme- Specification-of Letters Patent. Application il ta x5 27, 1905. sum no. 262,610-

diate portion 4- and inclined end portions 5 and 6. J These portions 4, 5, and 6, are provided with an upstanding flange 7, project:

ing from the'base'of the top which receives a resilient bed 8. This bed is shown as being approximately rectangular in cross-section and is held upon the upper portion of the frame by means of a strip 9 parallel with the upstanding flange'Z, which strip is provided with guide-lugs 10,'restingbeneath the base of the bed, the strip'9andthe upstanding flange comprising jaws for engaging the bed 8, which I jaws are held inclamped position by means of clamp devices illustrated as boltsll.

In Fig. 6 the base for the bed is of concavo convex form, as designated by the referencenumeral 12, and this base receives a resilentbed, such as a hose or tube 13, which may be stufiied'with any materialsuch, for example, as cotton-waste, as indicated by the referencenumeral 14. The ends of the hose or tube may be secured by means of the clamp-bar 15, which acts as amovable jaw cooperating with arigid jaw 16 at the end of the frame, said jaws being secured together by means of the adjusting devicesjl7.

In general practice will be utilized, and in order to prevent the disarrangement thereof the respective rear and front devices,'whichaline with each other,

will be secured together by a flexible connectionas, for example, a chain 18, which may pass around the end of each frame and be secured to the respective hooks 19 and 20.

From the foregoing description it-will be apparent that the pressure-relieving devices arein theform of skids or arches. When it :is desired to raise the wheelsso as to relieve the pressure upon the tires, the relieving defour of these devices vices are placed adjacent to the respective wheels and theengine or motor of the car is started,so that the hubs will roll up the inclined portions of the respective skids until they are adjacent to the horizontal portions of the bed. As these horizontal portions are of sufficient heights to raise the tire off the ground, the pressure willbe relieved and the inside pressure of the tire may be relieved during the time that the vehicle is not being used. By connecting up the alining skids any ed and the adjustments for the vehicles havingdifierent wheel-bases are provided for by shortening or lengthening the chain 18.

tendency of accidental displacement of the skids with respect toeach other will be avoidv IIO . I have illustrated and described the bed as the space utilized for the being of a resilient material, preferably rubber, but I may also utilize any other suitable material, such as soft pine, but the general arrangement of the parts'will in each case be the same.

1n the modified form (illustrated in Fig. 9) I have shown the devices arranged in the form of stalls for the reception of the motor-vehicles. These stalls may or may not be permanently attached to the floor or wall of the premises in which they are located. The supports consist of parallel vertical walls 21 and 22, connected by cross-bars 23. The vertical walls 21 and 22 carry resilient beds having horizontal portions 24 and 25, respectively, and inclined portions 26 and27,up which the rear wheels of the vehicle may roll onto the horizontal portions 24 and 25; These horizontal portions 24 and 25 will be a suflicient distance above the floor to accommodate wheels of the largest diameter, so that they will be adapted to support any-sized wheel now generally used on motor-vehicles.

The front wheels may be jacked up by suitable jacksas,for example, those designated by the reference-numerals 28 and 29and any number of these supports may be arranged within the premises, depending upon purpose of storing the vehicles.

Having thus described theinvention, what V is claimed as new, and desired to be secured by Letters Patent, is

1. A device of the class described comprising a base having a horizontal hub-receiving portion and an inclined portion for guiding the wheel-hub onto the horizontal portion; substantially as described.

2. A device of the class described comprising a base having a hub-receiving bed provided with an intermediate horizontal portion and oppositely-inclined guide portions; substantially as described.

3. A device of the class described comprisinga base having a rigid bed-receivingjaw and a movable jaw cooperating with the rigid jaw; substantially as described.

4. A device of the class described comprising a base provided with transversely-inclined braces, the upper portion of said base having an intermediate horizontal portion and oppositely-inclined end portions, and a yielding bed supported by said horizontal and inclined portions and conforming to the configuration thereof; substantially as described.

5. Means for elevating wheels provided with pneumatic tires comprising two alining bases having hub-receiving beds and an adjustably-attached flexible connection between the two alining bases; substantially as described.

6. A device of the class described comprising a vertical frame provided with a flange, a resilient bed on said frame for receiving a vehicle-hub, and an adjustable part attached to said frame and cooperating with said flange for holding the resilient bed in position; substantially as described.

In testimony whereof I hereunto aflix my signature, inthe presence of two witnesses, this 24th day of May, 1905.

JOHN C. WANDS.
